First most preferred embodiment according to smoking set of the present invention is shown among Fig. 1-8.Smoking set 10 comprises by active part 11 of cigarette coated papers 14 parcel and expansion lumen 12 and one by the fixing filtration members 13 of cigarette mouthpiece paper 205.Coated papers 14 preferably is processed into the cigarette paper with minimum thermal loss, for example has the cigarette paper of magnesium hydroxide charges, or its suitable heat resistant type cigarette paper of base, and with the paper of alumina sol-Gel Treatment.Will be discussed in more detail as following, active part 11 comprises the spice layer 21 of a thermal source 20 and charge releasing belt flavor steam and a gas when the hot gas with the thermal source of flowing through contacts.Steam enters expansion lumen 12, forms a kind of smog, enters then in smoker's mouth by cigarette holder 13.
, open as relevant pendent application No.89104936(as EP-A-0352108 corresponding to U. S. application No.07/223232) (this article is here as a reference) of the detailed explanation of institute.Thermal source 20 can comprise pure carbon basically, is preferably with catalyst or combustion additive.Thermal source 20 can be made and had one or more vertical passages that run through by activated carbon.The form of these vertical passages can be polygonal star, has long narrow angle and a little inner rim.The void volume of thermal source 20 can be greater than about 50%, and wherein the pore size between the active carbon particle is about the 1-2 micron.The weight of thermal source 20 is about 8/mg/mm, and density arrives between about 1.5g/cc at about 0.2g/cc.The BET surface area of the active carbon particle that thermal source 20 is used can be at about 50m/g in the scope of about 2000m/g.
Will go through as following, after giving enough oxygen, thereby thermal source 20 will burn and produce carbon dioxide basically.Also as discussed below, the emittance reflective sleeve 22 of active part 11 is non-flammable basically, can not burn between the operating period of smoking set 10.In addition, smoking set 10 constitutes in such a way, the gas that promptly flows through spice layer 21 has the oxygen content of minimizing (also as discussed below), thus the composition of spice layer 21 with pyrolytic, even and their temperature be high enough to they are ignited that they can not burn yet.When using smoking set 10(promptly to smoke) time, can not emit visible smoke basically.
The detailed structure of smoking set 10 is discussed now, and active part 11 is contained in the sleeve of a combination, comprises an emittance reflective sleeve 22 and an inner sleeve 23 that is positioned at emittance reflective sleeve 22.(just as used herein, unless otherwise indicated, " sleeve " speech refers to combined sleeve).Inner sleeve 23 is folded to provide a lip 24, and it makes carbon heat sources 20 remain on the position of dangling from the inwall of emittance reflective sleeve 22, thereby keeps an annular space 25.On the one hand spice layer 21 is maintained in the inner sleeve 23 between lip 24 and the thermal source 20, and netted intermediate plate or cup 26 are held in place the granular tobacco of spice layer 21 to allow simultaneously smog by to enter expansion lumen 12 on the other hand.Expansion lumen 12 is given the length and the outward appearance of smoking set 10 common cigarette.The open end portion 120 of inner sleeve 23 exceeds the openend of emittance reflective sleeve 22 and cooperates with expansion lumen 12.Coated papers 14 keeps together active part 11 and expansion lumen 12.Cigarette coated papers 14 preferably has enough porous, passes paper 14 and emittance reflective sleeve 22 to allow air, thereby is that thermal source 20 is combustion-supporting.Select as another kind, paper 14 also can be perforated in the zone around the emittance reflective sleeve 22 of thermal source, for example by static or laser beam perforation.
The aluminum inserts 27 that cooperates with inner sleeve 23 in intermediate plate 26 back is preferably sealed the openend of active part 11, only keeps the hole 28 that a heating steam passes through.Through hole 28 makes vapours increase its speed, expands in expansion lumen 12 then.Steam and the gas expansion in the expansion lumen causing saturated vapor cooling to be to form smog, so just being reduced to minimum level in mouthend piece 29,200 condensation on both, increased the smog that flows to the smoker.Can control the degree that expansion is also promptly cooled off by the size in change hole 28 and the volume of expansion lumen 12.
Get back to the structure of active part 11 now, the existence of annular space 25 makes has sufficient air stream to supply to thermal source 20 so that its sustained combustion and make the heat conduction to the outside drop to minimum level.Be above-mentioned reason, emittance reflective sleeve 22 is perforated and preferably has aperture area at least about 9.5%, and measures as follows and preferably have about 9.1 to about 15.1 gas permeability:
The gas permeability of emittance reflective sleeve 22 has determined the substance combustion rate of thermal source 20.Smoking set 10 be it is desirable to smoke about 10 times in (each minute smoke in two seconds 35 milliliters) under the FTC condition.If the substance combustion rate of thermal source 20 is too high, when whenever taking out one time, a smoker will carry more smoke.This is with comparative heat because of the gas that arrives spice layer 21.Yet, once just consuming more thermal source 20 owing to whenever take out, just may consume not less than 10 thermals source 20 so smoke.Similarly, if the substance combustion rate is too low,,, whenever takes out once and can only carry less smoke because gas is colder although the number of times of smoking can surpass 10 times.In addition, if the substance combustion rate is too low, the smoker prepare to smoke next before thermal source 20 may just extinguish.Have found that best substance combustion rate is between about 9mg/min and about 11mg/min.In order to obtain a kind of like this substance combustion rate of scope, the saturating property of measuring according to described method is preferably between about 9.1 and about 15.1.
Air stream in the active part 11 is that the path 10 6 in thermal source 20 enters spice layer 21.Preferably big as far as possible thermal source surface area and air streams contact so that the convection heat transfer' heat-transfer by convection of spice layer 21 is reached maximum, also make burning abundant as far as possible.Be same reason, passage 206 is not a simple cylindrical channel, but has the cross section of many sides, for example the anistree star cross section shown in the accompanying drawing.In fact, in most preferred embodiment, the surface area of the outer surface of the surface area ratio thermal source 20 of passage 206 is big.
For the radiation heat loss of smoking set 10 is reduced to minimum level, all inner surfaces of active part 11 all are processed to can reflection ray.For example, emittance reflective sleeve 22 is made by the paper that is coated with metal.Better structure is that emittance reflective sleeve 22 is made up of paper tinsel layer 71 in a ply of paper 70 and shown in Fig. 7 and 8.Paper tinsel layer 71 with the heat reflection backheat source 20 of thermal source 20 radiation so that it keeps heat, thereby it is following and extinguish to guarantee that it can not be cooled to its ignition temperature.The heat of the active part of reflected back also means to have more heat to be delivered to spice layer 21.
Can twine a paper slip or adopt the technology of other known manufacturing paper tube to make ply of paper 70 by spirality.Yet, preferably make ply of paper 70 and paper tinsel layer 71 together by an auxiliary equipment (being similar to the device of production conventional cigarette), make them become a pipe.In this most preferred embodiment, the overlapping edges of ply of paper 70 also bonds together mutually.Ply of paper 70 or loose structure or be perforated, thereby can obtain above-mentioned required gas permeability.Paper tinsel layer 71 is preferably made by 0.0015 inch aluminium foil, with its mold pressing to form the protruding hole of drum, then wheel load it flattening described hole, thereby make the paper tinsel of perforation more smooth.Although wheel load has been dwindled the hole to a certain extent, as long as the aluminium foil of mold pressing has at least 4% perforated area, preferably about 9.5% perforated area still can obtain desirable gas permeability.
Although paper tinsel layer 71 has reflected most of heat that is produced by thermal source 20, a part of heat still might escape into the outside.Reason is preferably improved paper used in the ply of paper 70 to stop burning, so paper can not ignited when using smoking set 10 to smoke for this reason.
At last, active part 11 has a reflection end cap 15, and it is crimped and is stuck in the emittance reflective sleeve 22.Lid 15 has one or more holes 16 to enter active part 11 to allow air.Hole 16 preferably is positioned to be covered on 15 the periphery.In most preferred embodiment, it is the hole that 0.080 inch equal angles separates that six diameters are arranged.Lid 15 has strengthened the radiant heat of the active part of reflected back.And if smoking set 10 some is loosening, cracked or fracture guaranteed that also thermal source 20 can not drop out in smoking set 10.When considering that at thermal source 20 between the secondary smoking with high-temp combustion and when smoking even when hotter, this point is crucial.Lid 15 has also blocked issuable any ashes when thermal source 20 burnings.
The external diameter of smoking set 10 is preferably 7.9mm, and is similar with conventional cigarette.The diameter of carbon heat sources 20 is preferably 4.6mm, and length is preferably 10.1mm, and the total length of active part 11 is preferably 26mm.The length of cigarette holder 13 is preferably 21mm, is divided into the acetate fiber filtration fraction 29 of 10mm and the tobacco pack portion 200 of 11mm.Expansion lumen 12 preferably 33mm is long, so the length overall of smoking set 10 is 79mm, is equivalent to traditional long size cigarette.In most preferred embodiment, lip 24 is that 2.6mm is wide.
Second most preferred embodiment according to the present invention is shown among Figure 10-13, and all the corresponding views with first embodiment is identical for any view of unshowned second embodiment among Figure 10-13.
In the embodiment shown in Figure 10-13 100, a separator 101 that is positioned at active part 110 separates the granular tobacco of spice layer 21 and the end of carbon heat sources 20.Have found that, compare with the embodiment shown in Fig. 1-8, the existence of separator 101 can provide even more heat to the end of the contiguous thermal source 20 of spice layer, this is because spread if having time before the thermal current of passage 206 arrives spice layer 21, so it can heat the more parts of spice layer end.The flash burn of spice layer 21 when the existence of separator 101 has prevented that smoking set 100 from lighting.When not having separator 101, the spark of coming through passage 206 suction when lighting might make spice layer 21 light, or flash burn, but when separator 101 is arranged, all diffusions on separator 101 of any this spark.Separator 101 is metal preferably, and as the aluminium dish, preferably through handling, handle as blackout on its surface, and it just can absorb the heat of thermal source 20 and heat radiation is arrived spice layer 21 like this.
The existence of separator 101 also provides other advantage.For example, it prevents to drop out through passage 206 from the granule of spice layer 21 (as cracked granular tobacco) and stops up the front end of the smoking set 100 between end cap 15 and the thermal source 20, does not drop out from smoking set 100 when perhaps having end cap 15.In addition, near or, can allow the granular tobacco of equal numbers in the spice layer 21 to compress by mobile separator 101 with different degree from intermediate plate 26 far away.Spice layer 21 compressing in various degree can make smoking set 10 have in various degree smoking resistance and different smoke features.At last, the separator 101 that the granular tobacco and the thermal source 20 of spice layer 21 separated also stops the fragrance mixture of granular tobacco to move on to thermal source 20, and they may stand pyrolytic and emit stink or pyrolysate at thermal source 20.
The 3rd most preferred embodiment according to the present invention is shown among Figure 14-21.All the corresponding views with second embodiment is identical for any view of unshowned the 3rd embodiment among Figure 14-21, if perhaps second enforcement does not have corresponding views then is identical with the corresponding views of first embodiment.
In the 3rd embodiment 300, eliminated the aluminum inserts 27 that has hole 28.On the contrary, intermediate plate 26 is used to the throttling action that provides required, to obtain the desirable expansion effect (although mapping not in scale, expansion lumen 212 cans be compared to expansion chamber pipe 12 most and grows) expansion lumen 212 in.Bore size on the intermediate plate 26 can be regulated to obtain desirable throttling action.
In addition, in the 3rd embodiment 300, the shape of the fluid passage by thermal source 200 is different.Different with the passage of polygonal star section, as the thermal source 220 among passage 206, the three embodiment passage 206 of a flower shape section is arranged, each projection of passage has all constituted a petal.Six petals are preferably arranged in passage 226.Flower shape section provides more efficient or more balanced heat conduction than star section, and by providing hotter control as the ashing tendency that reduces.Thermal source 220 itself be not major part be pure carbon, but include the carbon of metal nitride and above-mentioned necessary additive.The metal nitride that is used for the best of thermal source 220 is a nitrided iron.At relevant pendent and general known U.S. Patent application No.07/443,636(1989 submitted November 29) in describe this thermal source and advantage thereof in detail, this article is here as a reference.One of them advantage is also to have reduced the composition of cigarette except reducing carbon dioxide.Another advantage is to have higher ignition temperature.
At last, in the 3rd embodiment 300, the emittance reflective sleeve 22 and the perforated metal end cap 15 that in active part 211, have replaced the paper that is coated with metal of active part 11 to make with the single cup shell 222 that has end face 215.Cup shell 222 is preferably made by cold drawn aluminium.Hole 216 on the end face 15 is similar to the hole 16 on the end cap 15, but different with end cap 15 be that end face 215 is flat, and end cap 15 is curved surface shaped.Certainly, any required pore structure of cold drawn technology permission employing.Hole 216 allows to be used for lighting the end that flame (from match or lighter) is evenly distributed on thermal source 220 of lighting of smoking set 300.Be processed with groove on the cup shell 222.Its external diameter is limited by aluminium lamination 270, by groove 272 being pushed zone 271 and with its qualification.The external diameter of cup shell 222 is identical with the external diameter of expansion lumen 12, so coated papers 14 can be wrapped up a level and smooth surface.The internal diameter of the cup shell 222 at groove 272 places is such decisions, and promptly cup shell 222 cooperates with inner sleeve 23 tightly and securely.
Use and replace for metal cup-shaped 222 the sleeve 22 of metal-paper just to eliminate ply of paper 70.In addition, because the thermal capacity of cup shell 222 is bigger, when a user attempts to rekindle smoking set 300 and when not expecting that it has been lighted, cup shell 222 can be used to act on a fin.In smoking set 10 and 100, the attempt that rekindles smoking set may cause coated papers 14 to be lighted.Traditional cigarette also has this situation.Yet, in smoking set 300 since do not exist ply of paper 70 and since cup shell 222 than sleeve 22 bigger heat-sinking capacity is arranged, so reduced above-mentioned possibility of lighting coated papers.In addition, because expansion of metal when being heated, when using smoking set 300, the degree of contact reduces between cup shell 222 and the inner sleeve 23.So the heat on the sleeve 23 is less, has so also just reduced and put the painted chance of wrapping up in paper 14.
The invention provides a kind of smoking set so as can be seen, wherein the smog releasable material with smoke can be heated effectively by thermal source carbon containing or the part carbon containing, make the smoker avoid sucking glass fibre, heat loss on the spice layer wall is reduced to minimum level, and has the look and feel of conventional cigarette.Knowing this operator adopts other embodiment that does not describe also can implement the present invention as can be seen here.Embodiment as described herein is for illustrative purposes, and does not provide constraints, and the present invention only is subjected to the restriction of following claim book.
